  • Method Details

    • run

      void run(@Nullable FormSubmissionRequest request)

      This signal is emitted when a form is about to be submitted. The request argument passed contains information about the text fields of the form. This is typically used to store login information that can be used later to pre-fill the form. The form will not be submitted until webkit_form_submission_request_submit() is called.

      It is possible to handle the form submission request asynchronously, by simply calling g_object_ref() on the request argument and calling webkit_form_submission_request_submit() when done to continue with the form submission. If the last reference is removed on a WebKitFormSubmissionRequest and the form has not been submitted, webkit_form_submission_request_submit() will be called.
